Sorry for reposting, can someone help me with this please?

Dear NCL'ers,
As we know WRF's outputs are originally in Eta coordinates. I am trying to understand the logic of how the height (z) is calculated in NCL's wrfusergetvar function.
z = wrf_user_getvar(a, "z",time) ; grid point height
I expect that the height at each eta level should change as a function of x,y, and time.
Can someone tell me how the above function calculates this z? Is there an hydrostatic assumption? In other words, is the z
just geopotential height? Or is it the actual height itself?
Thank you,
Prashanth
